IMPROVEMENT IN SEAL-LOCKS.

Specification forming part of Letters Patent No. 179,370, dated June 27, 1876; application filed August 4, 1875.

To all whom it may concern:

Be it known that I, JOHN SWEENEY, ofthe city and county ofv New Haven, and State of Connecticut, have invented a new and Im- Y proved Seal-Lock; and I do hereby declare the following to be a full, clear, and exact description of my invention, such as will enable others skilled in the art to which it appertains to make and use it, reference being had to the accompanying drawing, which forms a part of this specification.

My invention relates to the construction of a bolt, which, in connection with a catch, hasp, and the seal, forms a seal-lock, while the same parts may be used with a padlock instead of the seal, as the ordinary fastening, consisting of staple, hasp, and padlock.

Figure l is a view of the lock in position, portions of the door to which the hasp is attached being shown. Fig. 2 is a vertical section through the post, in the plane of which lies the central line of the bolt. Fig. 3 is a view ofthe front end of the bolt, showing the flat side of the head, and the pert'orations through the same. Fig. 4 is a view of a seal of different construction from the one shown in Fig. 1.

H is the hasp made in the usual form, and attached to the door G in the usual way by a staple or bolt having an eye. E is an iron face-plate held to the post D by the screwbolts K'and n. T T are elevations or lugs corresponding in height to the thickness of the hasp II and seal I, and prevent the seal I and bolt A from turning.

plate c secured to it, so as to hold the catch in its place. The catch L is a rectangular oblong piece, free to slide vertically in the recess of the case F, and falls into one of the notches m m by its gravity, or by its gravity aided by a spring. The seal I is an oblong adapted for insertion in the hole W in the bolt shown in Fig. 3. When thus inserted and the bolt A forced back, the head of the screw-bolt K prevents its removal. These seals are made of any suitable frangible material. In Fig. 3 theperforation Y is shown, which allows a padlock to be used to retain the hasp H in the ordinary way, the bolt A answering the purpose of a common staple.

Thus constructed, the operation of 'these parts is easily understood. The bolt A being pulled forward, the hasp H, free to move in any direction, is passed over the head B and pushed back until it rests on the round part 0 of the bolt. The seal I is then also passed over the head B and onto the round parto, when itis turned to a vertical position. The bolt is then shoved back until the catch L drops into one of the notches 'm m, when the hasp H is securely held, and cannot be released without breaking the seal. When the seal is broken and the hasp pulled olf, the bolt may be pulled forward by turning it onefourth ot' a revolution, which raises the catch L, and causes it to rest on the round part o of the bolt, when it can be pulled forward and is ready for a repetition of the movements already described.

I claim as my inventionl. The bolt A, constructed with the flat and perforated head B, square part S, Vand round part 0, provided with the notches m m, and made to operate in connection with the hasp H and catch L in the manner described, substantially as shown and set forth.

2. The bolt A, constructed with the dat and perforated head B, square part S, and round part o, provided with the notches fm m, in combination with the catch L, face-plate E, hasp H, and seal I, of frangible material, interposed between the bolt-head and hasp, substantially as and for the purpose described.
